What used to be a woman's size 12 in 1968 is a woman's size 4 today; what used to be third-class is economy-class today. What changed? We've grown more sensitive: I'm not overweight, I still fit into a size 12. I'm not a third-class passenger: I'm a price-conscious individual that rides in economy-class.
Despite the name games, airline food hasn't changed much. Economy class meals still come in a wrapper, and business class meals come with real cutlery. This list shows the sometimes striking difference between what the different classes eat in side by side comparison photos.
